I used to live in Liverpool and knew "Auntie Mimi's" house / John Lennon's childhood home well. It was quite close to my parents' home.

One time, when I was showing the house to a friend from Liverpool University, the owner of the house came out and asked us how we knew about the house. She was a bit shocked when we showed her the map of "The Beatles' Liverpool" which showed this address.

She told us that she'd been plagued by tourists for several years and had always wondered why!
